If the rumors don’t make technology interesting, it’s the leaks that do.

Per AppleInsider, Twitter poster Chronic has posted a pair of screenshots of an alleged internal build of iOS 5, displaying settings for “Nuance Dictation” and “Nuance Long Endpoint.” In addition, a “Mic on space key” may provide further evidence of the rumored voice recognition support in iOS 5. The features are reportedly disabled for the developer build of iOS 5.

In May, it was suggested that Apple would deepen its relationship with Nuance, which makes voice recognition technology, in iOS 5. However, Apple neglected to demonstrate voice control features at last week’s Worldwide Developers Conference. After Apple’s keynote, several sources claimed that voice features weren’t ready in time for WWDC.

Apple has been expected to add complex voice command features to iOS since it acquired Siri, the developer of a voice search app that supported open-ended questions, last year.
